The gear. f

portionh 6 0 y *and* the` exible vhousing 6'2"" which* is' connected between thebody', 54 yand a similar c body 54,. fa-tits opposite end. The flexible shaft '60 may be formedwith the driving ends 64 and in the gear housing drivingly engage the shaft 66,

upon the end ofwhich a pinion 68 ismounted.

They gear housing I8 is provided with a. cover plate lllheldzin'position rby the cap screws llll that engage tapped openings in the housing. The cap screws 12 are provided with openings 14 to receive the Wire 16 which may be extended through all of the cap screws and have its ends connected by a seal member S to prevent tampering with the mechanism in the gear housing after the same has been assembled together and sealed.

The opposite end of the flexible shaft is mounted in driving relation to a plug member 18 which is formed with an enlarged portion 80 mounted in the bore S2 of a cylinder lock housing 84. The flexible shaft connector body 54 is adapted to screw threadedly engage in the tapped opening in the lock housing 84 and be secured therein against rotation by a pin member 86. The stud 18 is formed with a transverse Aslot 81 in its end to engage a lug 83 on the end of the lock cylinder 90. The lock cylinder may be of the usual type which is provided with locking tumblers 92 adapted to engage in any one of the slots 93 formed in the lock housing 84. It will be noted that six transverse slots 93 are provided, thus permitting one-sixth of a turn of Ithe lock and the locking of the ycylinder in a one-sixth turn position. The lock cylinder is held in position in the housing 04 by a spring washer 95. A key K is adapted to be inserted through the opening 9B for rotation of the lock cylinder.

'Ihe housing 84 may be formed with an external thread 98 and be extended through an opening |00 in the dashboard or instrument panel of an automobile. By means of a nut 02 and washer positioned on the back of the dashboard and a collar |04 positioned on the front of the dashboard, the assembly may be rigidly secured in position at the dashboard.

From the foregoing description, it will be apparent that when it is desired to change the adjustment of the spring'resistance member 22, that by inserting a key in the lock cylinder 00 and aligning the tumblers 92 so that the cylinder may berotated, the flexible shaft 64 will be rotated and through the pinion 00 and the gear 4E the screw member 26 in the governor will also be rotated.

Due to the fact that I have provided the adjustment described in the lock cylinder housing and the fact that there is a reduction between the pinion 68 and the gear 44, it will be obvious that a very minute adjustment of the governor can be accomplished. Thus, in the arrangement shown, one complete 4turn of the key will cause only onefifth of a turn of the screw member 26 in the gov# 'los e'rnor housing. From the foregoing it will be apparent that a comparatively simple,` yet effective and fool-proof remote control mechanism has been provided due to the fact that the cover of the governor and the gear housing are .both locked upon the governor by the spring washer 38. It will be apparent that tampering with any of the mechanism is thus prevented. The placing of a wire and seal through the cover bolts on the gear housing likewise will prevent unauthorized tampering with these members.

' In Fig. 2 I have shown a modification of the gear housing wherein the flexible shaft connector body 54 is connected through a boss 10a formed upon the face of the housing cover 10. It will be obvious that all of the parts may be the same and this modification is simply provided where it is desirable to have the .flexible shaft extend away from the governor toward its remote control position, rather than around as shown in Fig. 1.

While I have illustrated and described a specific embodiment of my invention, it willbe apparent to those skilled in the art that changes and modifications may be made in the exact detail shown, and I do not wish to be limited in any particular; rather what I desire to secure and protect by Letters Patent of the United States is:

l. In an apparatus of the class described comprising a spring housing, rotatable means in said spring housing, a bore communicating With the interior of said housing, and a cover plate for said housing having a lug projecting interiorly of said housing when the cover is in closed position, a contro-l shaft means adapted to engage said bore and said lug, releasable means interlocking with said shaft and' engageable behind said lug Iwithin the housing for sealingly retaining the shaft in operative position and holding the cover upon the housing, gear means on said shaft and a gear housing axially retained upon the spring housing by said shaft.

2. In an apparatus of the class described comprising a spring housing, rotatable means in said spring housing, a -bore communicating with the interior of said housing, and a cover plate for said housing having a lug projecting interiorly of said housing when the 'cover is in closed position, a control shaft means adapted to engage said rbore and said lug, releasable means interlocking with said shaft and engageable behind said lug within the housing for sealingly retaining the shaft in operative position-and holding the cover upon the housing, gear means on said shaft and a gear housing axially retained upon the spring housing by said shaft, and a flexible shaft operatively connected to said gear means for remo-te adjustment of said control shaft.

3. In an apparatus of the class described comprising a spring housing, rotatable means in said spring housing, a bore communicating with the interior of said housing, and a cover plate for said housing having a lug projecting interiorly of said housing when the cover is in closed position, a control shaft means adapted to engage said bore and extending through said lug to retain the cover upon the spring housing, releasable means interlocking with said shaft and engageable behindI said lug within the housing for sealingly retaining the shaft in operative position and holding the cover upon rthe housing, gear means on said shaft and a gear housing axially retained upon the spring housing by said shaft.

4. A device as defined in claim 1 wherein said gear housing is provided with portions interi-ltting with said spring housing, said portions comprising means to prevent relative displacement of said housings in an angular direction about said shaft.
